In Victorian London, Genevieve Timmons poses as a spiritualist to swindle wealthy mourners—until one misstep lands her on death row. Then a stranger arrives to make her an offer. The lord he serves, Mr. Pemberton, has been inconsolable since the tragic death of his fiancée. If Genevieve can perform a séance to briefly reunite them, she will win her freedom. At the Somerset Park estate, however, Genevieve finds that that the woman was murdered, and she teams up with the dashing Mr. Pemberton to coax the killer into the light.
